Technical products are facing different changes during their lifecycle. These changes can have drastic impacts to the product, either towards its structure or the effort for the implementation. If platform elements used in various products within a product family, the change impact can be capital. Based on existing methods, we developed an approach to propagate changes, triggered by a specific

The approach consists of matrix-based methods and allows the propagation via different domains, for example components, functions and variation attributes. Change causes can be linked more easily to the product architecture and the change impact can be traced via different relevant product domains. The approach is illustrated by an industrial case study shown in this contribution.
